xenharmonic (microtonal wiki)

Omnitetrachordal MODMOS scale
7L+13s
20 tones (8+4+8)

Tetracot MODMOS. Comes in 3 forms!

P = 4.1745609664
Q = 9.4523018119 (4/3 = 3L+4.5s)

L = 60.00 to 171.43 cents (118.65 cents @ P, 143.28 cents @ Q)
s = 0.00 to 60.00 cents (28.42 cents @ P, 15.16 cents @ Q)

9/8 = L+3s (171.43 to 240.00 cents)
4/3 = 3L+5s (480.00 to 514.29 cents)
MOS generator = L+2s (171.43 to 180.00 cents)

notable EDOs: 27, 34, 41, 61, 75
